Full-Stack Software Engineer

About

I’m a Senior Software Engineer with 3+ years of experience designing and scaling systems across advertising, payments, and blockchain platforms. I focus on full-stack development with React, Next.js, and Nest.js, and have extensive expertise in databases, distributed systems, and API design.

At Unimedia, I improved real-time ad processing throughput by over 200%, modernized legacy systems into scalable TypeScript backends, and mentored 20+ engineers to deliver production-ready apps. My work consistently reduces costs, increases performance, and enables teams to move faster.

I thrive at the intersection of technical problem-solving and team enablement, bringing a passion for clean, maintainable code and scalable architecture.
